W. W. CLARKSON, OF BALTIMORE, MARYLAND.

CARD-PRINTING- PRESS.

Specication of Letters Patent No. 20,039, dated April 27, 1858.

To all whom 'it may concern:

Be it known that I, WM. W. CLARKsoN, of Baltimore, in the State ofMaryland, have invented a new and useful Improve-- ment in Card-PrintingPresses; and -I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a side elevation of a card printing press constructed withmy improve- Fig. 2, is a vertical longitudinal section of the same, andFig. 3, a plan of a detached part of the same.

Similar letters of reference in each of the several figures indicatecorresponding parts. l The nature of my invention consists, 1st, 1n thecombination by a peculiar and exceedingly simple arrangement ofmechanism, of the slide which feeds the cards singly from the card box,the bed plate which supports and carries the impression form and theinking roller which inks said form, whereby, with the simple revolutionof the driving crank shaft, the inking roller can be moved forward andmade to ink the form, and the card at the same time carried forward andleft upon the guides below the platen and directly above the form, theinking roller and the card feeder again returned back to their originalpositions and the form brought up with a heavy pressure and caused toprint the card lying upon the platen and then moved down out of the wayready for another operation.

It consists, 2nd, in the combination of the vibrating slide which feedsthe cards singly with the grooved guides which receive and retain thecards below the platen, and directly above the impression form, whilebeing printed.

It consists, 3rd, in the peculiar manner of adapting the card boX forcards of different widths, lengths and thicknesses, to wit by having itsside, front and back boards or strips adjustable laterally,perpendicularly and longitudinally by means of slo-ts and set screws.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A, represents the frame of the machine; B, the impression form bed; C,the rollers which ink said form; D, the slide to which the inkingrollers are attached and which feeds the cards under the platen anddirectly above the impression bed; E, the platen and F, the guides whichreceive the cards from the'slide D; F, the card boX or hopper; Gr, thecharging ink rollers, and H, the laterally vibrating roller whichdistributes the ink uniform-ly over the said charging ink ro-ller.

The combination of the impression form 'bed B, slide D, and inkingrollers C, is accomplished`by means of a toggle lever I, I, pitman J,crank shaft K, connecting rod L, rock shaft M, slotted arm N, andconnecting rod O, arranged as shown in the drawing.

The upper fulcrum of the toggle lever I, I, is arranged to play freelyup and down in a slot a, of an 'extension b, of the form bed and thelower fulcrum to a pivoted adjust-- able bearing c. And the frontfulcrum or pivot of the connecting rod L, is arranged ina slot it, ofthe rock shaft M, and the pivot of its rear end attached fast to thepitman of the crank shaft K. By thus coupling the upper end of thetoggle lever to the form bed and the fulcra or pivots of the connectingrod L, to the rock shaft M, and pitman J, said lever can, after it hasdrawn the bed to a proper position to have the inking rollers ink thebed, descend to the position shown in red' in Fig. 2, independently ofthe form bed, and thereby draw the crank shaft K, rock shaft and slottedarm M, N, slide D, and inking rollers C, C, forward to the positionshown in red and thus effect the inking of the form which is arranged onthe bed B, and the removal of a single card, by means of the lip ci, ofthe slide from the card hopper F, and the deposit of the same upon thesupporting guides F, F, as illustrated in blue. And by having the lowerend of the lever adjustable by means of setscrew c, of the pivotedbearing c, the form bed can be adjusted to rise to a greater height tosuit the thickness of the form or any changes which may take place inthe relative position of the parts to each other.

rIhe form bed is attached fast to two vertical rods f, f, which playfreely up and down through guides g, g, and the top of the frame. Theserods have screw threads on their upper ends in order to receiveadjusting stop nuts L, It. By thus arranging the form it always has aparallel movement and the extent of its descent can be regurods f, f,accomplishing this end, and thus 22 lop the inking of the form by therollers C, C, can always be insured.

The rear end of the rod O, of the slide D,

is attached to the arm N, of the rock shaft M, by means of a swivel eyeS, a screw thread formed on rod, and two thumb nuts j j. By thusconnecting the slide the eX- tent of its forward movement can beregulated to suit various sizes of cards, the return or backwardmovement of said slide being regulated by means of an adjusting stop O1,of the frame K.

The card box or hopper is attached to a stationary head board 7c, in amanner that its base stands just the thickness of one card above the topof the slide. By this arrangement the lip (Z, of the slide can only takehold of one card at a time. The sides m, m, of the card hopper or boXare made adjustable laterally and vertically by means of the set screwsZ, Z', so as to suit cards of dierent lengths and thicknesses. The frontguides n, '11 are also adjustable longitudinally by set screws and slotsp p so as to suit cards of different widths. Y

The rockshaft M, N, owing to being cou` pled to the connecting rod L, bymeans of a slot and pin is not Capable of returning back after it haseected the forward movement of the slide, and therefore a scroll springl), is provided, as shown, for throwing it back to its proper position.

That I claim as my invention and desire to secure by Letters Patent, is-

l. The combination, by the peculiar arrangement of mechanism specified,of the slide D, which feeds the cards singly from the card boX, the bedplate B, which supports and carries the impression form, and the inkingroller C, which inks said form; substantially as and for the purposesset forth.

2. The combination of the vibrating slide D, which feeds the cardssingly, with the grooved guides E, F, which receive and retain the cardsbelow the platen, and directly above the impression form while beingprinted, substantially as and for the purposes set forth.

The peculiar manner of adapting the card box F for cards of dierentwidths, lengths and thicknesses, to wit; by having its side front andback boards or strips adjustable laterally, Vperpendicularly andlongitudinally by means of slots and set screws, substantially as andfor the purposes set forth.

The above specifica-tion of my improvement in printing press signed byme this 17th day of February, 1858.
